[Boatanchors] How much is too much?

[rbethman]

Jack,

I would strongly suggest grounding all the other antennas NOT in use for 
the "working" station setup.  The 2 watt level could easily take out the 
front of "some" solid state front ends.

Use a T/R setup *IF* you run separate TX/RX.

I've got a Heath coax switch and a B&W one.  I switch all "other" rigs 
to ground by the use of those two switches.  The "single" in-use TX/RX 
is tied to an E.F. Johnson 250-39.  It takes the beating of a BC-610 on 
the Tx side, and has an R-390A hung off the RX side.

I also use an external relay to the R-390A for the "break-in" terminals 
on the rear.

As usual, YMMV.
